Summary

Abstract:
Sea ice concentration observational data from the FNMOC Ocean QC (Quality Control) process are posted in near real-time to the USGODAE server. These files contain all of the unclassified in-situ data used to initialize the US Navy NOGAPS model, and all of the climate and background (forecast) values used in the QC process. The sea-ice concentration retrievals were obtained by the Special Sensor Microwave/Imager (SSM/I), which is an instrument carried by the Defense Meteorological Satellite Program (DMSP) series of satellites. The SSM/I is a seven-channel, four-frequency, linearly polarised, passive microwave radiometer. The fundamental quantity measured is the total power received by the radiometer, which can be converted to the antenna temperatures and brightness temperatures. The sea-ice concentration is calculated from the brightness temperatures. |
